Click to Dial will not work if SELinux is enabled

[blak3r]

When SELinux (Security Enhanced Linux) is enabled, click to dial will not be able to open a socket with fsockopen. You'll get an error #13 Permission Denied error.

Instructions for disabling this are here: http://archives.ryandaigle.com/articles/2005/9/27/mythweb-howto-fix-fsockopen-function-fsockopen-unable-to-connect-to-127-0-0-1-6543-permission-denied-error

I've also updated the troubleshooting section on the Wiki. If anyone knows a way to allow fsockopen to work without completely disabling SELinux please post notes here.

Note: asteriskLogger also uses fsockopen but since it's run as a system process instead of by apache. Security settings do not apply to it.
